T0 ztZZ whmn it may concern.-

Be it known that we, EMMERICH MARKo- VITS, residing at Barwaldstrasse15, Berlin, and FRIEDRICH GUTHMANN, residin g at Niedstrasse 32,Friedenau, near Berlin, Germany, subjects of the King of Prussia,Emperor of Germany, have invented a certain new and Improved Process.for the Manufacture of a Preparation for Preserving Meat and the Like,of which the following is a specification.

The present invention relates to a process for the manufacture of apreparation for preserving meat, fish, game, and the like; and itsobject is to provide the meat with a thin coating by painting it withthe preparation, by which coating it will be protected for considerabletime against putrefaction.

The essentially novel feature of the invention lies in the fact that thepreparation itself, which is entirely innocuous to health, prevents thereception and development of putrefying germs, so that it is alsoabsolutely impossible for germs of putrefaction which may have been onthe surface of the meat to spread. The meat to be preserved retains itscolor, and the formation of maggots on the meat or the protectivecoating by the presence of flies is absolutely prevented.

The process for the manufacture of the pre serving preparation is asfollows: About forty per cent. of gelatin and fifteen per cent. agaragarare dissolved in thirty-five per cent. distilled water with two percent. of salt and boiled for some time. A jelly-like mass is thusobtained, to which, after cooling, about seven per cent. of pure alcoholand one per cent. of sodium salicylate are added. This mass afterthorough mixing is again boiled with about ten per cent. of water, sothat a fairly liquid preparation is obtained which congeals on cooling.For use it is liquefied by heat and painted evenly on the meat or thelike to be preserved. The coating congeals in a few seconds and forms anentirely smooth and pliant covering.

We declare that what we claim is 1. Process for the manufacture of apreparation for preservging meat and the like in which gelatin andagar-agar are dissolved in distilled water and salt and boiled, the massproduced being mixed after cooling with pure alcohol and sodiumsalioylate and again boiled with distilled watersubstantially asdescribed.

2. Process for the manufacture of a preparation for preserving meat andthe like in which about forty per cent. gelatin and fifteen per cent.agar-agar are dissolved in thirtyfive per cent. distilled water and twoper cent. salt, and boiled for a considerable time, the jelly-like massproduced being mixed after cooling with about seven per cent. of purealcohol and one per cent. of sodium salicylate and again boiled withabout ten per centpof distilled water, substantially as described.

In witness whereof we have signed this specification in the presence oftwo witnesses.
